\"\"Regular Expressions (abbreviation: RegEx<\/strong>) are signs which built in an intelligent and easy to understand system. We have the ability to use this system in Openquran <\/a>and improve our work much faster and even exactly. If users of OpenQuran doing research to the counts and calculations of Letters\/words\/verses and there gematrical values than its very important to understand the idea behind RegEx<\/strong>. <\/span><\/p>\n

RegEx is mostly used in programming languages, databases, search engines, Spam filters etc. It\u2019s easy to understand but needs from us more the artistic talent on how to build the RegEx definitions. There are also a lot of Sites which have more detailed informations on how to use this small powerful language, but the would like easily show how to use with the Arabic language and specially for the Quran.<\/span><\/p>\n

The practical part<\/big><\/strong><\/span> (Using in Openquran)<\/big><\/strong><\/span><\/p>\n

To use RegEx in Openquran we have to set the<\/span> checkbox “Regular expressions<\/strong>“, and choose the<\/span> table (translation) in which we want to search; here we\u00b4ll choose the<\/span> table quran <\/strong>which is automatically installed with OQ.<\/p>\n
